Oh my god, I waste SO much time organizing my MP3s. I have a playlist at home on my entertainment center PC which consists of albums in their entirety, it's about 100 albums by various artists I'm interested in at the moment. On my portable MP3 player on the other hand I try to narrow it down to just the hits since I only listen to it about 15-30 minutes at a time and really want the songs to jump out at me- right now I have 231 songs by 56 artists. I've been meaning to revise my portable, the last time I've went through and cleared it out and put new songs on was about a year and a half ago. It generally takes me about 3-4 hour minimum to cycle through all my albums and decide which songs to include, so I keep putting it off.
